The importance of packaging for plastic products

 In today's world, plastic products have become an integral part of our lives. From household items to industrial tools, plastics are used in almost every sector. However, with the increasing use of plastic products, the importance of packaging has also increased significantly. Packaging plays a crucial role in protecting and preserving plastic products throughout the supply chain. In this blog post, we will discuss the importance of packaging for plastic products.

 

Firstly, packaging helps to protect plastic products from damage during transportation and storage. Plastic products are often fragile and can easily get damaged if not handled carefully. Proper packaging ensures that the products are protected from moisture, dust, and other external factors that can cause damage. Moreover, packaging also helps in reducing the risk of theft and tampering during transportation.

 

Secondly, packaging helps to preserve the quality of plastic products. Plastic products are susceptible to degradation over time due to exposure to light, heat, and moisture. Proper packaging helps to prevent these factors from affecting the products and ensures that they remain in good condition for a longer period. This is particularly important for plastic products that have a longer shelf life, such as medical devices and electronic components.

 

Thirdly, packaging plays a vital role in branding and marketing plastic products. The packaging design and quality can significantly impact the consumer's perception of the product. A well-designed and high-quality packaging can create a positive impression on the consumer and increase brand loyalty. Moreover, packaging can also be used as a tool for differentiation in a highly competitive market.

 

Fourthly, packaging helps to reduce the environmental impact of plastic products. Plastic waste is a significant environmental concern, and proper packaging can help to reduce the amount of plastic waste generated. Packaging that is reusable or recyclable can significantly reduce the environmental impact of plastic products. Moreover, packaging can also be designed to use fewer materials, thereby reducing the overall carbon footprint of the product.

In conclusion, packaging is an essential aspect of plastic products that should not be overlooked. Proper packaging helps to protect and preserve the quality of plastic products, enhances branding and marketing efforts, and reduces the environmental impact of plastic waste. As such, businesses that deal with plastic products should give due consideration to packaging design and quality to ensure that their products are well-protected and marketed effectively.

What is a surface printing?

 

China Plastic injection molding products processing technology

Plastic parts surface printing is a widely used technique in the manufacturing industry that involves applying graphics or text onto the surface of plastic components. This process is commonly used to enhance the aesthetics of products, provide branding or labeling information, and improve overall product visibility.

There are several methods of plastic parts surface printing, each with its own advantages and limitations. One of the most common techniques is pad printing, which involves transferring ink from a silicone pad onto the plastic surface. This method is ideal for printing on irregular or curved surfaces and can produce high-quality, detailed prints.

Another popular method is screen printing, which involves pushing ink through a fine mesh screen onto the plastic surface. Screen printing is suitable for larger print areas and can be used to achieve vibrant colors and intricate designs. However, it may not be ideal for complex shapes or small print areas.

Digital printing is another option for plastic parts surface printing. This technique involves directly printing the desired graphics or text onto the plastic surface using specialized digital printers. Digital printing offers flexibility in terms of design customization and can produce high-resolution prints. However, it may not be as cost-effective for large production runs compared to other methods.

In addition to these techniques, there are also various considerations when it comes to selecting the right ink for plastic parts surface printing. The choice of ink depends on factors such as the type of plastic material, desired print durability, and environmental requirements. Common types of inks used for plastic parts surface printing include solvent-based inks, UV-curable inks, and water-based inks.

When implementing plastic parts surface printing, it is crucial to ensure proper surface preparation to achieve optimal print quality. This typically involves cleaning the plastic surface to remove any contaminants or oils that may interfere with ink adhesion. Additionally, pre-treatment methods such as corona treatment or flame treatment may be necessary to enhance ink adhesion on certain types of plastics.

Plastic parts surface printing offers numerous benefits to manufacturers. It allows for customization and personalization of products, making them stand out in a competitive market. It also provides a cost-effective solution for branding and labeling requirements, eliminating the need for additional labels or stickers. Furthermore, surface printing can enhance product visibility and improve user experience by providing important information or instructions directly on the product.

In conclusion, plastic parts surface printing is a versatile and effective technique for enhancing the appearance and functionality of plastic components. With various printing methods and ink options available, manufacturers have the flexibility to achieve their desired print quality and design customization. By utilizing plastic parts surface printing, businesses can create visually appealing products that leave a lasting impression on consumers.

 Overview:

• Parts Design 

• (client may provide completed 3D files)
  The tooling process begins with a completed and checked part design. CNMOULDING can optionally optimize your design before tooling to lower your costs and ensure that your design will work well.
• Parts Prototyping (if necessary)
  If you would like to validate your parts design with a machined piece that you can see and feel, Cnmoulding can use Computer Numerical Control (CNC) techniques to prototype your parts.

• Tool Design

• At this stage the tool is designed, using the information from your completed tools and molds design

• Tool Check and Mold Flow Analysis

• The tool design is validated for correctness.
• Tool Fabrication (including use of Computerized Numerical Control (CNC) and Electrical Discharge Machining (EDM) technologies)
  The tool is precisely fabricated according to the validated design.

• First Shots To Client

• Once the injection molds are made, the first test shot samples will be sent out soon after via an international courier. Once sent, these usually take around 2-5 days to arrive.

• Tool Modifications and Texturing

• At this stage, Cnmoulding completes the tool and makes any required changes to bring the tool into the approved spec. Changes made to bring the tool to spec (specifically excluding design changes, which are always charged) are made free of charge.
  At this stage, texturing also takes place, which is normally the last stage before mass production.

• Mass Production Run or Export

• At this stage, parts are produced and delivered to the customer, or the tool is released for export use.

Technical Topics:

Molding begins with tooling. No matter how good the design, if the tooling is not up to the task, the quality of the parts will suffer.

The Molding Machine

Achieving consistent dimensions and quality requires up-to-date molding machines, operating to specifications, with precise position and pressure control capabilities. The basic construction of a molding machine is fairly straightforward.

Material is fed in through a hopper into a screw and barrel where it is heated to a molten condition. The melt is then injected under high pressure into the mold while the mold is held closed with the high force of a toggle or hydraulic ram. The goal is to melt resin in a very uniform and repeatable fashion, inject it into the mold under very precise and repeatable pressure conditions, and hold the steel temperatures in the entire flow system very stable. After the molten plastic is solidified, the mold is opened and the gear is ejected. It then continues to cool in the open air.

There are many handling and pre-processing requirements for injection molding materials. Engineering polymers quite often must be dried to a specific dew point before use. When parts are made, runners are formed that some shops regrind and put back in the melt. This quite often raises more quality concerns than the slight savings in material expense may justify, and CPIM uses only virgin material.

Injection

The method of injecting the plastic into the mold is very important. In most cases, the plastic should be injected under high pressure very quickly to maintain the good characteristics of the melt completely during the injection. As the mold cavity fills, the injection pressure should be held at the same high value and the speed of injection slowed to maintain that pressure. At the moment when the part is filled, and the molding machine switches over from injection to a pack & hold condition, the plastic melt is held at the same high pressure. This pressure is held for as long as it takes to freeze the gates and achieve the highest weight possible for the molded part.
